Sorry, I interpreted your question wrongly. We call a multi polygon a
geometry object having more than one polygon. That one is supported.
N-layer will be supported once and is (theoretically) feasable by the
same algorithm-set but not supported now.
Overlay operations are currently still intersection / union, that state
didn't change after review.
